V This invention relates generally to washing machines, and particularly to one of small dimensions in the prime-mover thereof. I

The main objectof this invention is .to pre-' vide a novel form of washing'machineand drive therefor especially adapted foruse in localities where electric power expensive.

The second object is to provide a-novel form of 'prime' mover which will be wateroperated,

is not'available or too;

quiet in operation, simple to 'n anufacture and devoid oidelicate or intricate parts. I

The third'ooject is to provide a water propelled washing machine in which thepropellingjwa'ter can be employed for rinsing purposes if desired. These, and other objects will become more apparent from'the specification following as illustrated; in the v accompanying drawings, in w h? I I r If. Eig. 1'is aside elevation of themachine.

Referring in detail to the drawings, the device consists principally of three elements, namely a rockableicylinder 20 and supporting frame-'21 at one end of the cylinder; and a second supporting frame'22 at the opposite end of the cylinder whichconstitutes a housing-forthe, prime mover. The cylinder 20 is provided with aremovable closure 23 whichcanbe snapped into its removal and application tothecylinder. 7

The cylinder 20 has its end 24 provided with a '76 trunnion 2 5 which journals in theframe 2i} The I cylinder, 20 has its end 26 provided with an elongated trunnion 27which neeen' opening 27A'= formed therethrough; along its entire length;

' The trunnion 27- journals in the side wall 28 of the; frarnei'22. ongthe trunnion 27 is keyed a.

- curvedarm 29'with projecting "stops 30 formed at opposite endsthereoflwhich areoutside of thecurved face 31 of the arm 29.

:Rising-from'the floox 3l- -A isthe lower back wall 32 whichdoes not join' the lower end of the Jwa11128I Outside of 'the wall 32 is formed a flange;

33 which,with the wall "fil -forms a catch basin having an outlet34' atth'e-bottorn thereof. The side frames 21 jand 22 are held in spaced relation by means of 'the tie rods 352 "The cylinder 20 is ,pr'

37lof'the cock 36is placed in the open position. The frontof the name -2 2-is provided with an opening 38 through which can be inserted theblock of the primehiover. This consists of a pair of parallel cylinders 39, preferably "upright and. having their lower ends closed by means of the headsiQ and which. are held in spaced'rela- ,tionship b y-a crosstie .41-inwhich is rotatably mounted a tripvalve 42 havingjan', enlarged end portion 43,-a' reduced intermediate portion 44'and 'a' still further reduced end portion 45 which pro jects through the closed end 46 of the tie,41 and has'mounted on the outer end thereof afull throw disk 47 on whichisipivoted the head-48 head 48 lies between the steps 30.

Journaled in the 1 cross tie 41 is the tap vane ided with a waste 'eee 36 which discharges into the catch basin formed Into the member 42 there projects the manually rotatable control valve 60 which has an opening along almost the entire length thereof and which has one side of its innermost closed end 61 cut away as shown in Figs. 5 and 14. The control valve 60 is provided with a cutaway portion 62 which is adapted to register with the. opening 63 in the passageway 53. The control valve 60 is provided with an opening 64 which extends across its closed end a short distance therefrom and can register'with the opening 65 in the trip valve 42,'which opening can register with the opening 66 in the top of the cross tie 41. A pipe.-

67 connects the opening 66 with the outer end of the trunnion 27. The valve 60 is provided with an encircling flange 68 by means of which it is held within the trip valve 42 by the cap 69 through which the valve 60 projects. 4

Over theopening 38 is placed a cover plate 70 which forms a bearing for the valve 60 on the outer end of which is placed a dial 71 by means of which the valve 60 may be placed in either the rinse position 72, the run position 73 or the fill position 74. O

On the outer end of the trunnion 27 is mounted a walking beam 75 which is joined at its ends .by means of the connecting links'76 to the'pistons 77 in the cylinders 39.

It is desirable to provide the interior of the cylinder 20 with a pair of longitudinal ribs 78 and 79 for the purpose of expediting the tumbling action of the articles being washed.

The operation of .the device is as follows As.- suming that clothes have been placed in the cylinder 20 and that the dial 71 has been turned to the fill position 74 and that the valve 60 has been coupled up to a water supply line, preferably by means of a hose, the parts will now be in the position shown in Fig. 10 in which water can flow directly from the' Valve 60 through theopenings 64, 65 and 66, and then through the pipe 67 into the cylinder 20. V I

When a sufiicient amount of water is admitted to the cylinder 20 the dial 71 is turned to the run position (as shown in Fig. 9) in which it will be noted that theopening 64 does not register with the opening 65, but the opening 62 does register with the opening 63, causing the pistons 77 to move, and, through the member 29, to reverse the trip valve 42. a a I Obviously, unless some means is provided for insuring the completion of the rocking movement of the trip valve 42 in either direction the device could not function properly, and it is for this reason that there ,is provided the ,full stroke mechanism, including the members 29and 47 to be rocked and water admitted to the cylinder for rinsing purposes while it is in motion.

It must be understood that the control valve 60 does not rock with the trip valve but is held in one of the positions 72, 73 or 74 by means of a spring-urged ball 60-A which is mounted in the plate 70 and consists in corresponding depressions in the valve 60.

It can thus be seen that by a very simple arrangement of parts an economical quiet running machine has been produced which, under the control of one valve, allows the machine to be filled or operated for washing purposes or used for rinsing purposes.

-We are aware that many forms of washing machines have been constructed in the past, therefore we do not claim such devices broadly,

but we do intend to cover all such forms and modificationsthereof as fall fairly within the appended claims.

We claim:

1. A water motor comprising a pair of spaced parallel cylinders, an oscillating valve mounted between said cylinders having intake and exhaust channels formed therein, said cylinders having ports formed therein adapted to register with said channels, a tubular control valve within said oscillating valve through which water may enter the intake channels, a walking beam mounted between said cylinders, pistons in said cylinders connected to said walking beam, and a valve actuating mechanism between said walking beam and said valve for oscillating said valve.

2. A fluid operatedmotor having in combination a pair of parallel cylinders, a cross he between said cylinders, an oscillatable trip valve mounted in said cross tie having communicating passageways between theinterior thereof and said cylinders whereby water may be caused to enter or escape from said cylinders, a tubular control valve having an inlet opening at one end. and an outlet port near its opposite end, said control valve being adjustably mounted within said trip valve and having another port therein capable of being'brought into communication with the passageways in said trip valve, a rock shaft mounted between said cylinders above said trip valve and parallel with the axis'of the trip valve, a walking beam secured on said rock shaft,

, a piston in each of said cylinders connected Ito said walking beam, an arm secured on said rock shaft having a pair of radially projecting stops, a throw disk mounted on said trip valve, a headed pin having its head pivotally attached to said throw disk and having its opposite end mounted in an oscillatable guide, said head occupying a position between said arm stops, a spring on said headed pin between its head and said oscillatable guide, and'a dial for manually setting said control valvewith relation to said trip valve;

3. A fluid operated motor having in combination a horizontal rock shaft, a walking beam secured to said rock shaft, a pair of vertical parallel cylindersdisposed on opposite sides of said rock shaft each of said cylinders having a piston-therein provided with a connecting link to its respective end of the walking beam, an oscillatable trip valve for .connectingpassageways communicating with said cylinders, a, normally stationary control valve adjustably mounted within said trip valve, said control valve constituting a means for admitting water to said trip valve, and means actuated from ,said, rock shaft for moving said trip valve to, either of its extreme positions of travel at the end of each
